Light-controlled nanomachines embedded in a polymer can control its shrinking and expanding
A research team from France has made the first nanomachines that can be switched into reverse gear with light. Embedded into a piece of polymer gel the tiny machinery can be used to shrink and expand the material. Nanomachines can already perform functions such as assembling molecules, but many molecular motors only work in one direction.
